Abstract

The invention relates to an identity verification method and system based on voiceprint recognition, and the method comprises the steps: obtaining the voiceprint features of voice data after the voice data of a user, the identity of who will be identified, is received, and constructing a corresponding voiceprint feature vector based on the voiceprint features; inputting the voiceprint feature vector into a pre-trained generated background channel model, so as to construct a current voiceprint discrimination vector corresponding to the voice data; calculating the spatial distance between the current voiceprint discrimination vector and a pre-stored standard voiceprint discriminating vector of the user, carrying out the verification of the identity of the user based on the distance, and generating a verification result. The method can improve the accuracy and efficiency of identity verification of the user.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for identity verification based on voiceprint recognition. Background technique [0002] At present, the business scope of large financial companies involves multiple business areas such as insurance, banking, and investment. Each business area usually needs to communicate with customers through various means of communication (such as telephone communication or face-to-face communication, etc.). Verifying a customer's identity before any communication takes place becomes an essential part of keeping your business secure. In order to meet the real-time requirements of the business, financial companies usually use manual methods to analyze and verify the identity of customers. Due to the huge customer base, relying on manual discriminant analysis to verify the identity of customers is not accurate and efficient. Contents of the invention [0003] The ...
